Common HEP UNIX User Environment - Combinatorics


Few comments about combinatorics. The aim of this project is clearly not modest. If you simply consider the following attempt to measure the "combinatorics" and the complexity: Multidimensional problem
	Complexity = M x G x W x S x K x Cxt x Tty x O
where
M:	number of machines and UNIX platforms
        AIX, HP-UX, SunOS, Solaris 2, IRIX, ULTRIX, OSF/1, Convex, (Linux ?)
G:	number of desktop types 
        Plain Motif, Openwin and desktops like COSE and HP-VUE
W:	number of window managers
        mwm, twm, fvwm, dtwm, etc.
S:	number of shells
        sh, csh, ksh, bash, tcsh, zsh
K:	number of keyboards
	PC-like, NCD-like, VT-like, HP-like, SunOS-like, etc.
Cxt:	number of contexts 
	telnet, rlogin, klogin, rsh, etc.
Tty:	number of terminal emulator types
        VT100, VT200, xterm, etc.
O:	other factors 
	number of terminal devices, network aspects, etc.
Then the complexity represents a bog number of different behaviours!

But, we need something, otherwise, it will take a great amount of time for each user to set a proper and consistent environment
